Answer:

Maria purchased 9 CDs

Step-by-step explanation:

Maria spends $84.00 on CDs. The first CD is $12, the rest $9

As the CD have different price , first we have to discount the price of the first one, and then we divide the rest by $9

Price First CD = $12 ,

We buy the first , so we get the rest of money 84-12=72

Price Rest =$9 , with the money that left , we can buy 72/9= 8

Total= 1 +8 =9
